Blast furnace slag granulation insulation device

Equipment use:
This equipment is used to receive hot melt slag from blast furnace, after heat preservation, air quenching and granulation after release.

• Rapid Quenching Granulation System: Adopts high-pressure water jet or air-cooled atomization technology to achieve <0.5-second rapid solidification of molten slag (1450-1550℃), forming glassy granules with 90%+ uniformity (particle size 0.1-5mm) and minimal crystalization.
• Intelligent Thermal Insulation Module: Integrates multi-layer refractory materials + vacuum insulation panels, maintaining post-granulation slag temperature at 600-800℃ with <5% heat loss/hour, enabling direct heat recovery (up to 3.2 GJ/ton slag) via built-in heat exchangers.
• Closed-Loop Dust Control: Equipped with negative-pressure cyclone dust collectors and wet scrubbers, achieving <30mg/m³ particulate emissions—far below industrial standards—while recycling 99% of water used in granulation for cyclic reuse.
• Adaptive Process Control: PLC-based system dynamically adjusts water/air flow, insulation intensity, and conveyor speed based on real-time slag composition (CaO/SiO₂ ratio) and discharge volume, ensuring stable granule quality across varying blast furnace operating conditions.

Core Features & Benefits

• Efficient Granulation: Adopts advanced atomization/granulation technology to quickly solidify molten blast furnace slag into uniform, small granular slag with stable properties.
• Insulation & Energy Retention: Equipped with professional insulation systems to maintain slag temperature during processing, facilitating subsequent resource recycling (e.g., heat recovery, building material production).
• Environmental & Economic Value: Reduces slag waste and dust emissions, turning industrial by-products into reusable materials while cutting energy consumption.
